Abstract
Description
Technical Field
[0001] This utility model belongs to the field of paper product processing technology, and more specifically, it relates to an adjustable gray cardboard calendering device. Background Technology
[0002] Adjustable grey board calendering equipment is a type of machinery used for calendering grey board. By adjusting parameters such as pressure and temperature, the surface of the grey board becomes smoother and flatter, improving its quality and appearance. Adjustable grey board calendering equipment can precisely adjust the pressure between the calendering rollers according to different grey board thicknesses and calendering requirements. Common pressure adjustment methods include hydraulic and mechanical types. Adjustable grey board calendering equipment heats the grey board during operation; however, currently used adjustable grey board calendering equipment has limited applicability to grey board of different thicknesses during steam heating. For example, for thicker grey board, the heat transfer to the interior of the board takes a long time during steam heating, easily leading to a large temperature difference between the surface and the interior. Therefore, a new type of adjustable grey board calendering equipment is needed. Utility Model Content
